HD-DVD / EVO muxer (H264+AC3)

[shon3i]

@deank, just one note, from HDDVD spec, vbv-buffersize should not exceed 14745 for main video, while maxrate should not exceed 29400

Thanks!

These values I use for AVCHD written to DVD discs. I'll change it accordingly for HD-DVD, too.

Looks like it works well, tested with an external x265 and forced no reencode and I have a perfect HDDVD folder, I do have one problem though, when I encode with 2 pass VHQ in MultiAVCHD the evo's created show some weird colour problems, every few frames the colour becomes oversaturated then returns to normal, I can send you a link to a test evo showing the problem if you want, this isn't new it happened with previous versions too. I'll continue testing and see if I can find out more.

i want to ask you if there is some way co create an EVO stream file with more than 1 audio and subtitles its posible to make something like that??

Hi!

As of v.34.02, BD-RB uses a version of x264.exe with a filesize of 6,336KB. Using this version of x264.exe together with:

HDDVD_COMPLIANT=1
USE_NAL_HRD=0

results in an .M2TS file that MultiAVCHD indicates is "HD-DVD compliant". Choosing to "quick process" as HD-DVD (takes about 15 minutes), either with or without transcoding, yields a file that plays back video as a "slide show" with audio at normal speed.

With prior versions, I was able to replace the BD-RB x264.exe with an older x264.exe with a filesize of 1,097KB without causing problems with BD-RB's performance. Doing so also allowed MultiAVCHD to successfully convert the .M2TS file to a properly playing HD-DVD "package".

Unfortunately, with v.34.02 of BD-RB, swapping in the older version of x264.exe prevents BD-RB from functioning properly.

Although I can, of course, use BD-RB with its proper 6,336KB x264.exe and NOT including:

HDDVD_COMPLIANT=1
USE_NAL_HRD=0

and then use MultiAVCHD, in the "standard" method to convert to HD-DVD (takes about two to three hours), I'd obviously prefer to be able to use the "quick process".

Your thoughts and/or suggestions will be appreciated.

What if you use:

HDDVD_COMPLIANT=1
USE_NAL_HRD=1

and x264.exe from multiAVCHD? It is not that old version.

I know this is an old thread but I'm currently experimenting with HD DVDs and it seems the only muxer available.

Has anyone tried to modify it for other fps? Just changing the framerate in the code won't help. Always crashes. Well actually the version ALWAYS crashes, even if I compile the not modified code.

Not having luck with the updated hddvdmux. The resulting files are completely out of sync with the audio.

Went back to MultiAVCHD 4.0 and while the process is successful, the resulting video files are nowhere near the quality of modern x264.

Could someone please compile a modern x264 version with the pre r1510 NAL hrd long start code? (Not sure if it needs to be 32 bit, but I'd guess so since the 64 bit standard version of x264 in MultiAVCHD is clearly labeled.

They may help you.

Not to unduly necro a thread, but is this the command that multiAVCHD uses to make HD-DVD compliant x264 streams? If so, does it matter if I'm using multiAVCHD 4.0 or 4.1? Also are there any different options needed for 23.976 vs 29.97 content?

For context, I'm trying to do some sub-SD encodes for an HD-DVD player since the format supports it (352x480 specifically). Old as it may be, your suite is still the only free option out there for making HD-DVD content.
